OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 489,138, dated January 3, 1893.

Application filed February 8,1892. Serial No. 420,649. (No model.)

To a. whom it may oonccrm.

Be it known that I, ABRAM Q.ALI.1s, a citizen of Prattsburg, in the county of Steuben and State of New York, have invented a new and useful Improvement in Oil-Stoves, of which the following is a specification.

This invention relates to improvements in oil stoves.

The principal object of my invention is to increase the air supply to the burners of the stove, so as to produce a large flame and a complete combustion.

My invention has the further objects to so construct the burners that easy access may be had thereto-for lighting, extinguishing or cleaning the same and for trimming the wicks; and to provide the stove with si mple means for directing the escaping heat through either of the draft-holes located behind the main utensil openings.

In the accompanying drawings consisting of three sheets:Figure l is a front view of my improved oil stove, showing one-half of the stove in elevation and the other half in vertical section. Fig. 2 is a horizontal section of the stove in line 1-1, Fig. 1. Fig. 3 is a cross section thereof in line 2-:?, Fig. 1'. Fig. 4 is a top plan view of the stove. Fig. 5 is a horizontal section of the stove-top in line 3-3, Fig. 1. tical section of one of the burners and its chimney. Fig. 7 is a horizontal section in line 4-4, Fig. 6, looking down. Fig. Sis a similar view in line 5-5 Fig. 6,looking upward, showing the lever for looking the upper part of the chimney in place. Fig. 9 is a top plan view of the upper part of the chimney and the lower plate of the stove-top, showing the manner of supporting the upper part of the chimney when raised. Fig. 10 is a vertical section in line 6-6, Fig. 9. v

Like letters of reference refer to like parts in the several figures.

A A represent the upright side-frames of the stand which are connected near their lower ends by-tie-rods a.

B is hollow the stove-top supported upon the side frames A and having the usual front utensil holes I], closed by removable lids b, and rear draft-holes b which are covered by Fig. 6 is'an enlarged ver:

wick tube extending centrally through the fount, and F" the tubular wick surrounding said tube. The'latt'er opens at its lower end through the bottom of the oil fount and conducts the air upwardly which is supplied to the inner side of the flame; The upper end of the wick tube is provided with a cap or hood which is composed of a perforated cylindrical wall f extending above'the top of the wick tube and an imperforate top plate .or deflector f which is secured to the top of the perforated wall and closes the upper end of the wick tube.

f 2 is a perforated tube which surrounds that part of the wick tube which projects above the oil fount and from which it is separated by an annular passage through which the air entering through the perforations of this tube flows to the outer side of the flame. The parts of the burners thus far described are all old and well known.

G is an air feeding tubearranged within the .wick tube and extending upwardly through the imperforate top or deflector f, thereof. This air tube is open atitslower end to receive air from the interior of the wick tube and is provided above the defiectorf with a hollow distributing 'head G. The latter is composed'of an imperforate top plate 7 and a perforated lower or side wall g which latter is connected with the upper end of the air feeding tube. The internal air srrpply reaches the flame artly through the perforated wall f at the top of the wick tube and partly through the distributing head above the top defiectorof the wick tube. The first mentioned internal supply is delivered in fine jets against the root ot' the flame, and the last named supply is delivered above the deflector in .a lateral and downward direction against the inner side of the flame at a higher eleva- 5. tion'. By this means all of the air which is supplied through the wick tube is brought in intimate contact with the flame and utilized for supporting combustion and none is allowed to escape directly upwardly into the chimney where it would impair the draft and cool the products of combustion.

The chimney of each burner is preferably constructed of cast-iron and is divided horizontally into two separable sections H H. The lower section II 'rests loosely upon the supporting plate D. The upper section II is supported upon thelower section by an annular shoulder 71- formed at its lower end and resting upon an outwardly projecting-annular .zo flange 7t formed at the upper end of th'elower section.

It is an annular deflector arranged within the upper part of the chimney and separated from the surrounding wall of the upper chimney section by an annular space or passage j. This deflector has the form of a' truncated cone and is secured at its upper end to the adjacent wall of the upper chimney section, the deflector fitting closely against the chimney at this point to prevent the passage of air between the upper end of the deflector and the chimney. The deflector is formed at its lower end with an outwardly projecting annular flange i'resting against the inner surface of the lower chimney section and provided with air passages or openings/i, where'- by the space inclosed bythe chimney is placed in communication with the air passage 3' between the conical deflector and the upper chimney section.

It are air openings or passages formed in the flange at the upper end of the lower chimney section and through which the surrounding air enters the annular air passage j. The air entering the passage 3' through the openings in, is directed downward by the deflector 1 and caused to dive through the air openings in the flange of the deflector and enter the chimney. The upper part of the flame is thus supplied with air on its outer side tion of the chimney sections, and on its inner side by the air rising through the airfeeding tube G, thus furnishing the upper part as wellas the base of the flame with an ample volume of air on all sides, whereby a perfect combustion is produced and the size of the flame considerably increased. The body of air in the passage 3' surrounding the deflector 1 acts as a non-conductorwhich checks radiation of the heat through the chimney. The passage j also forms a chamber in which the air is heated before it enters the chimney, whereby the fresh air is supplied to the flame dncing a smokeless combustion.

The lower chimneysectiou is provided with through the annular air passage at the 'unc-L in the most advantageous condition for pro-.

icense a door L having openings L closed by panesof mica through which the condition of the flame maybe observed. The upper chimneysection is arranged with its upper end in an opening m formed in the bottom plate M of the stove-top and is provided on opposite sides with lugs or projections m. which fit in notches m formed in opposite sides of the opening m. when the upper chimney-section rests upon thelower section, as shownin Figs. 1, 3, 5 and 6. Upon raising the upper section of the chimney sufficiently to bring its lugs m above the bottom plate M of the stove-top and giving the section'a partial turn to break the coincidence between its lugs and the notches m as shown in Figs. 9and 10, v

the lugs by resting upon said top-plate, will support the upper chimney section in the position shown by dotted lines in Fig. 6,

in which position the lower end of said sec i tion clears the upper end of the lower chimney section. The latter rests upon rearwardly extending ribs or guide-ways N arranged on the supporting plate D. At the rear end of each of these guide-ways is arranged a raised flange or stop n. After raising the upper chimney section and suspendingit from the stove-top, as just described, and opening the door of the lower section the latter may be slidbackwardly on' its ways into the position shown, by dotted lines in Fig. 2, the backward movement of the chimney-section being limited. by the stop n. In

this position of the parts, the space above the burner is unobstructed, so that ready access is had to the burner for lighting, extinguishing.or cleaning it or for trimming or renew-'- ing the wick. After raising the upper chimney-section and removing the nut-of the fastening bolt d the supporting plate D may be swung upward on its rear supporting lugs d, to gain access to the parts of the burner under the same. The. parts are again returned to their normal position by moving the lower chimney-section forwardly over the burner and lowering the upper section-by turning it so as to bring its lugs into register with the notches in the lower plate of the stove-top. The upper chimney-section is preferably locked in this position by a catch or lever O pivoted to the underside of the stovetopand engaging with its inner end in a notch or recess '0 formed in the chimney section between its lugs m and'a shoulder 0 arranged on the section below said lug, as'shown in Figs.

6 and 8. Upon swinging this lever out of the notch ofthe upper chimney-section, the lat tor-is released.

The latter are connected with the reservoir by pipes Q is a warming shelf arranged above the oil reservoir P and hinged at its front edge tothe rear edgeof the supporting plate D, the shelf being provided with hooksor knuckles g which engage with .loops q formed on the I supporting,'plate, ae'shown in Fig. 2. lhe
